Were there ever plans to do a beach scene in any version of the script? Or maybe Nancy was going to use someone's swimming pool?
I don't think so, but who knows? When I first saw the still I did think it was an odd one because it seemed completely unrelated to the film. But then there are those stills with Nancy and Chris Pennock that are also completely unrelated to the film.
Perhaps DC told Nancy he was thinking of doing a remake of
The Ghost in the Invisible Bikini, but with loads of blood and gore, naturally, and to also be shot at Lyndhurst with Nancy in the lead? The still was his way of getting a jump on publicity shots?
(After all, they already had a photographer on site who was already getting paid to take photos, so knowing DC he would have seen it as a perfect way to save money.) But that film, like a third DS film, never came to be?
No? Well, then who know why on earth Nancy ever posed in a bikini?
